Question :

Which of the following is essential for observing diffraction?

a. Two coherent source

b. A narrow slit

c. A screen

d. White light

Answer :

Option b. A narrow slit is the correct option.

A narrow slit is essential for observing diffraction.

• The bending of light around the edges when it passes around an edge or through a slit is called the diffraction of light.

• The slit must be in the order of wavelength of light.

• Diffraction of light is caused by one wave of light which is being shifted by a diffracting object.

• The only condition of diffraction is that the width of obstacle must be either less than or equal to the wavelength of light .
